Comparing Static Analysis of Earth Dam Strength with Space Monitoring Data [PDF]
E3S Web of ConferencesThis study focuses on the stress-strain behavior of a shallow earth dam, using the Kattakurgan reservoir in Uzbekistan as a case study. The analysis examines the primary forces acting on the dam, specifically gravity forces and hydrostatic pressure.

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Attenuation of Coda and Body Waves for Tbilisi and Surrounding Area, Georgia
International Journal of GeophysicsThe attenuation of high-frequency seismic waves was investigated in the crust beneath Tbilisi and the surrounding territory by analysing 225 local earthquakes that occurred from 2008 to 2020 and were recorded by eight seismic stations.
